LX2750CLQ

Overview

The LX2750CLQ is a power management integrated circuit manufactured by Microsemi Corporation. It features a single input supply PWM controller combined with an LDO controller, supporting dual output configurations. The device utilizes Step-Down (Buck) Synchronous and Linear (LDO) topologies. It operates within a switching frequency range of 200kHz to 2MHz and requires a supply voltage between 10V and 16V. The component is designed for surface mount installation in a 16-WFQFN exposed pad package and functions within an operating temperature range of 0°C to 70°C.

Feature Summary

• Integrates a single-input PWM controller with an LDO controller for dual-output power management
• Supports Step-Down (Buck) Synchronous and Linear (LDO) conversion topologies
• Operates with a wide switching frequency range from 200kHz to 2MHz
• Designed for surface mount applications in a compact 16-WFQFN package

Applications

• Power supply systems requiring dual output regulation
• Industrial control equipment power management
• Communication infrastructure power distribution
• Data center server power modules

Procurement Notes

Verify the specific manufacturer designation, as Microsemi Corporation's semiconductor assets were acquired by Microchip Technology. Confirm the package type matches the required 16-WFQFN configuration and ensure the operating temperature range meets the application's environmental specifications. Check for RoHS compliance status if required by regulatory standards.

Selection Notes

Select this component when a single IC solution is needed for both synchronous buck and linear regulation from one input source. Ensure the input voltage stays within the 10V to 16V range and that the thermal design supports the 0°C to 70°C operating limit. Verify that the 200kHz to 2MHz switching frequency aligns with system EMI requirements and inductor selection constraints.

Part Context

The LX2750 series belongs to Microsemi's portfolio of power management controllers. This specific model combines high-efficiency switching regulation with low-noise linear regulation capabilities. It is part of a family designed to simplify power architecture by reducing component count and board space compared to discrete solutions.

Replacement Considerations

Consult official Microchip or Microsemi documentation for direct pin-to-pin replacements. Cross-reference with other models in the LX2750 series for variations in package or temperature rating. Verify functional compatibility before substituting.
